VEHICLE WIPER

DESCRIPTION OF A USEFUL MODEL

The utility model relates to vehicles, the working conditions of high-altitude ones require a slight increase in driving speeds, especially to traction means equipped with technological, predominantly necessary equipment, emergency rooms, in particular, for cleaning roads and washing roads, streets and other areas sheet materials on the surface of the road surface, for earthworks and road works, etc.

Known creeper rotary working orgasis of an agricultural machine, which has tefvod from the shaft support the power of the specified machine (see RU 2153990, class. 60 K 17 / 06,2000).

A well-known gooshenshigel self-propelled maple, for example) of a tractor is transmitted to the input shaft from a gearbox (see SU 379422, class B 60 K 17 / 08.1973).

A known transmission of a vehicle, including a creeper, kinematically associated with a gearbox k with a transfer case. When the vehicle is operating at slow speeds, 1 foot is transmitted from the secondary shaft of the gearbox to the creeper shaft and then to the input shaft of the transfer case (see SU 979178, class B 60 K 17/06, 1982),

(options)

the creeper reducer is carried out from one of the nodes of the transmissions of the vehicle, which limits the range of adjustment of the vehicle's moving speeds when operating at slow speeds, and in the event of failure of individual transmission nodes can lead to downtime of the vehicle.

The technical result that can be achieved using the inventive utility model is to expand the range of adjustment of vehicle speeds when it is running at slow speeds and to increase the reliability of the vehicle.

To achieve the specified technical result, two design variants of the vehicle speed reducer are proposed.

According to the first embodiment, the creeper includes an autonomous hydraulic motor and gearbox located between the transfer case and the front axle of the vehicle and comprising a housing connected to the transfer case crankcase and a pair of gears that are constantly engaged, one of which is mounted on the central shaft of the gearbox with the possibility of transmission torque from the hydraulic motor to the front axle through the clutch, and the other is connected to the output shaft of the hydraulic motor.

According to the second embodiment, the creeper includes an autonomous hydraulic motor and gearbox located between the transfer case and the rear axle of the vehicle and a housing mounted on the chassis frame of the vehicle, and a pair of continuously engaged gears, one of which is mounted on the central shaft of the gearbox with the possibility of transmission torque from the hydraulic motor to the transfer case shaft, which serves to drive the front axle, through the clutch and then to the front drive shaft one hundred, and

the other is connected to the output shaft of the hydraulic motor, while the central shaft of the gearbox is aligned with the drive shaft of the front axle of the transfer case.

When using the proposed vehicle speed reducer, comprising, according to the first embodiment, an autonomous hydraulic motor and gearbox located between the transfer case and the front axle of the vehicle and including a housing connected to the transfer case crankcase and a pair of gears that are constantly engaged, one of which is mounted on the central the gearbox shaft with the possibility of transmitting torque from the hydraulic motor to the front axle through the clutch, and the other is connected to the output the hydraulic motor shaft, as well as the autonomous motor containing the second embodiment and a gearbox located between the transfer case and the rear axle of the vehicle and including a housing mounted on the chassis frame of the vehicle and a pair of gears that are constantly engaged, one of which is mounted on the central gearbox shaft (coaxial drive shaft of the front axle of the transfer case) with the possibility of transmitting torque from the hydraulic motor to the front axle drive shaft of the transfer case ki through the clutch and further to the driveshaft of the front axle, and the other is connected to the output shaft of the hydraulic motor, power is taken to drive the vehicle when it is operating in slow speeds from an autonomous hydraulic motor, which allows a wider range of vehicle speeds to be obtained. In addition, the independence of the operation of the creeper from the operation of the transmission units of the vehicle will maintain the vehicle in working condition even in the event of failure of the individual said units. The essence of the claimed utility model is illustrated in the drawing, where

FIG. 1 shows the construction of the proposed creeper according to the first option / its implementation;

FIG. 2 shows the design of the proposed creeper according to the second embodiment of its reduction.

Presented in FIG. 1 running gear contains an autonomous hydraulic motor 1 and a gear 2. The gear 2 is located between the transfer case 3 and the front axle of the vehicle (not shown in the drawing). The gearbox 2 contains a housing 4, and gears 5 and 6, which are in constant gearing. The housing 4 of the gearbox 2 is connected to the housing 7 of the hydraulic motor and to the crankcase 8 of the transfer case 3. The gear 5 is mounted on the central shaft 9 of the gearbox with the possibility of transmitting torque from the hydraulic motor 1 to the front axle via the clutch 10. The gear 6 is mounted on the output shaft 11 of the hydraulic motor 1 .

In accordance with the second embodiment of the invention (Fig. 2), the creeper includes an autonomous hydraulic motor 1 and gear 2. The gear 2 is located between the transfer case 3 and the rear axle of the vehicle (not shown). The gearbox 2 includes a housing 4, and gears 5 and 6, being in constant gear. The housing 4 of the gearbox 2 is mounted on the chassis frame of the vehicle (not shown in the drawing) and connected to the housing of the hydraulic motor 1. The gear 5 is mounted on the central shaft 9 of the gearbox with the possibility of transferring 1 torque from the hydraulic motor 1 to the shaft 12 of the transfer case 3, which serves to drive the front bridge, through the clutch 10 and further to the driveshaft of the front axle. The gear 6 is mounted on the output shaft 11 of the hydraulic motor 1. The central shaft 9 of the gearbox 2 is aligned with the shaft 12 of the front axle drive of the transfer case 3.

When the motor 1 is turned on, the torque from the output shaft 11 is

4

main motor through a pair of gears 6 and 5 and the clutch 10 is transmitted to the Central shaft 9 of the gearbox 2 and then to the front axle of the vehicle. In accordance with the second embodiment, a reduction gear transmission from the hydraulic motor to the front axle of the vehicle is reduced by a dash transfer case 3. The engine of the vehicle is idling.
